Abstract

There is provided a package for a non-aqueous electrolytic battery by which water invasion from outside is lowered and adhesion strength is improved over the long term, and a non-aqueous electrolytic battery having a lengthened life and high reliability. In a package for a non-aqueous electrolytic battery having a bag construction to store a battery content made by adhesion of a part of a lamination film comprising a metal layer and a resin layer, the adhesion part holds a structure capable of reacting with or absorbing an element which diffuses from the battery interior inwardly to the battery interior side.

Claims

exact text as granted — not AI-modified

What is claimed is:  
     
       1. A package for a non-aqueous electrolytic battery, having a bag construction to store a battery content made by adhesion of a part of a lamination film comprising a metal layer and a resin layer, wherein the adhesion part holds a structure capable of reacting with or absorbing an element which diffuses from the battery interior outwardly to the battery exterior side. 
     
     
       2. The package for a non-aqueous electrolytic battery of  claim 1 , wherein adhesion of the film is performed by using a hot-melt adhesive in the form of tape containing a structure capable of reacting with or absorbing an element which diffuses from battery interior. 
     
     
       3. The package for a non-aqueous electrolytic battery of  claim 2 , wherein adhesion of the film is performed by using a hot-melt adhesive in the form of tape containing, in parallel to the longitudinal direction, a filament structure capable of reacting with or absorbing an element which diffuses from battery interior. 
     
     
       4. A battery using the package for a non-aqueous electrolytic battery of  claim 1 . 
     
     
       5. A battery using the package for a non-aqueous electrolytic battery of  claim 2 . 
     
     
       6. A battery using the package for a non-aqueous electrolytic battery of  claim 3 .
